Rotten to the core? Drivers of the vertical profile and accumulation of internal tree stem damage

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Trees are important above‐ground carbon sinks in savanna ecosystems, yet consumption of internal wood by decomposers (e.g. termites and microbes) creates uncertainties in tree biomass accounting.

A North–South Metallicity Asymmetry in the Outer Galactic Disk—Evidence for the Pericentric Passage of the Sagittarius Dwarf Galaxy

The Astrophysical Journal Letters
We present maps of the mean metallicity distributions on the Galactocentric R – Z plane at different azimuthal angles using red clump stars selected from the LAMOST and APOGEE surveys.

Fluctuating salinity during development impacts fish life histories

Journal of Animal Ecology, EarlyView.
Global freshwater ecosystems are increasingly threatened by salinisation. Salinity levels not only rise but also fluctuate due to extreme climate events and human activities. This study shows that stable elevated salinity accelerates reproduction in a freshwater fish, but fluctuations in salinity reduce reproductive output, with sex‐specific effects on

Teaching assistants' experiences in delivering additional support to pupils in UK primary schools

Support for Learning, EarlyView.
Abstract Teaching Assistants (TAs) (may also be known as Learning Support Assistants or Classroom Assistants) are important members of staff within a school environment. There is guidance on the deployment of TAs; however, little is known about how these recommendations are operationalised in a school setting. The aim of this research was to explore TA

Assessing the Association between the Globular Cluster NGC 4147 and the Sagittarius Dwarf Galaxy

The Astronomical Journal
The potential association of the globular cluster (GC) NGC 4147 with the Sagittarius (Sgr) dwarf spheroidal galaxy has been proposed due to their comparable locations and radial velocities. However, there are still debates about this connection.
